  • Publication number: 20100054418
    Abstract: The present invention provides an X-ray detecting element that can obtain radiation images by X-rays of different energies by irradiation of X-rays a single time, without positional offset arising. A first scintillator is provided at an outer side of a sensor portion and a sensor portion of one surface side of a substrate. A second scintillator is provided at another surface side of the substrate. X-rays that are irradiated from the one surface side or the other surface side of the substrate are converted into light at the first and second scintillators. The sensor portion detects light that is illuminated from the first scintillator of the one surface side, and the sensor portion detects light that is illuminated from the second scintillator of the other surface side of the substrate.

  • Publication number: 20090322719
    Abstract: The present invention provides a detection element that can suppress generation of a residual image. A sensor portion includes a semiconductor layer, an upper electrode and a lower electrode. The semiconductor layer generates charges due to light being illuminated thereto. The upper electrode applies a bias voltage to the semiconductor layer. The lower electrode collects charges that have been generated at the semiconductor layer. The charges that have been generated at the semiconductor layer are collected and accumulated by the lower electrode. In the detection element, a saturation prevention circuit (diode and second bias line) is provided through which the accumulated charges flow-out when the charges that have been generated at the semiconductor layer are collected and a voltage level of the lower electrode becomes a saturation prevention voltage level Vs.

  • Patent number: 7608832
    Abstract: An image detection device has an image detector equipped with a detection section having a charge generation section that receives irradiation of electromagnetic waves and generates charges, a storage capacitor in which two electrodes are disposed so as to oppose one another and which accumulates charges generated at the charge generation section, and a TFT switching element for reading out charges accumulated in the storage capacitor. At a time before a point in time of reading out of charges from the storage capacitor via the switching element of the image detector, a reference potential of the storage capacitor is varied by a variable Cs power source, and leak current sufficiently flows before reading out of a charge signal from the image detector. Leak current is thereby reduced sufficiently at a time of reading out the charge signal.

  • Publication number: 20090261338
    Abstract: An active matrix substrate includes a plurality of transistors. A source electrode is connected with a data signal line, and a drain electrode is connected with a pixel electrode in each transistor. The source electrode is located on a semiconductor layer, and at least a portion of the drain electrode is overlapped with the gate electrode. A gate insulating film covering the gate electrode of each transistor has a thin section having a reduced film thickness, at a portion where the gate insulating film is overlapped with each gate electrode. An overlapping area of the thin section with the source electrode is smaller than an overlapping area of the thin section with the drain electrode. Thus, the active matrix substrate can prevent the generation of short-circuits between the signal lines (between the data signal line and a scanning signal line) in a TFT forming region, while guaranteeing TFT characteristics.

  • Publication number: 20090118974
    Abstract: A fuel injection control apparatus of an internal combustion engine is provided with a fuel injection valve that injects fuel directly into a combustion chamber and a controller. When the engine is cold started (i.e., YES in step S10), a first fuel injection is performed and the injected fuel is spark ignited during the compression stroke, and a second fuel injection is performed during the expansion stroke. The controller selects, according to exhaust emissions, one of a first fuel injection rate and a second fuel injection rate that is lower than the first fuel injection rate as a fuel injection rate during at least the expansion stroke and injects fuel at the selected fuel injection rate. The second fuel injection rate is selected as the fuel injection rate of the second fuel injection and the start timing of the injection is advanced compared with the conventional injection start timing (i.e., when a reference fuel pressure is used) (steps S11 to S16).
